Faults - Lincoln Electric APEX 3 Series Operator's Manual

APEX ® 3 SERIES TIG PENDANT MANUAL
When an inclinometer is available in the weld head and
the Outside Track Ring is selected on the Track /Setup
screen, the CAL selection button icon is displayed
at the bottom of the Motion Controls screen and the
current weld head position is displayed directly above
the icon, see FIGURE 33 - Service Screen Motion
on page A-38 and FIGURE 34 – Service Screen Step
Over. Pressing the CAL selection button will calibrate
the weld head inclinometer. A warning is given prior to
the calibration indicating that the calibration process
requires the weld head to travel completely around the
pipe – any obstructions should be removed.

While welding, the flow of shielding gas and/or cooling
water can be monitored if the appropriate hardware is
present. For gas flow, the required level can be speci-
fied. The Faults Screen On Settings shown in
FIGURE 35 provides access to these features.

Water flow is detected by an ArcLink
Cool Arc unit.

Use the Left Toggle to select GAS or WATER and then
the Right Toggle to turn monitoring ON/OFF. With gas
monitoring turned ON, two additional controls are
made available; a LEVEL selection to input the re-
quired level of gas flow using the Right Toggle and a
REF value which will display the current gas flow value
when the PURGE button is pushed.
With the Water Fault turned ON, the water flow will be
monitored during welding. If it's determined that water
is not flowing, the weld will be terminated and a mes-
sage will be displayed indicating a Water Fault.
If the Gas Fault is turned ON, gas flow level will be
monitored during welding and compared to the re-
quired flow level. If the monitored flow level is less than
the required level, the weld will be terminated and a
message will be displayed indicating a Gas Fault.
If the Gas and Water Faults are turned OFF, welding
will continue regardless of the level of gas or water
flow. If the appropriate flow sensor hardware is not
present in the system then the corresponding fault(s)
should be disabled.
